Abstract
In a light detection device, a control unit performs a first charge transfer process for transferring charge generated in a charge generation region to a charge storage region by applying an electric potential to a transfer gate electrode so that a potential energy of a region immediately below the transfer gate electrode is lower than a potential energy of the charge generation region and a first read process for reading an amount of charge stored in the charge storage region. In the first charge transfer process, the control unit applies an electric potential to an overflow gate electrode so that a potential energy of a region immediately below the overflow gate electrode is lower than the potential energy of the charge generation region.
